Abstract

An auxiliary tool handle for attachment to the free end of a hand operable, rotatable tool comprises a body having a cavity therein for receiving a ratchet mechanism. A cover plate closes the cavity and covers the ratchet mechanism. The ratchet mechanism comprises a rotatable circular disc member having teeth about the periphery thereof and an axial extension projecting through the cover plate for insertion in a corresponding recess of the regular handle of a tool. A pair of pawl members are mounted in the cavity of the body and are normally biased by springs into driving engagement with the teeth of the disc member. A pivoted cam member having an operating portion projecting through the cover plate is operative selectively to move either of the pawl members out of teeth engaging position to determine the direction of rotation of the body relative to the disc member.

Claims

1. An auxiliary tool handle comprising:

a relatively thin, disclike body having a cavity therein;

a cover plate for closing said cavity;

an annular bead in said cavity and axially spaced from said cover plate;

a rotatable disc member supported between said cover plate and said annular bead in bearing contact therewith, said rotatable disc member having a plurality of teeth evenly spaced about the periphery thereof and having a portion projecting axially therefrom through the center of said cover plate for insertion in a cooperating recess in the handle of a tool;

a supporting ledge in said cavity axially spaced from said cover plate and generally parallel thereto;

a pair of pawl members supported between said ledge and said cover plate;

spring means for normally biasing said pawl members into engagement with said teeth; and

a cam member disposed between said pawl members and having a portion projecting through said cover plate and operable to pivot said cam member to selectively move said pawl members out of engagement with said teeth for controlling the direction of rotation of said body relative to said disc member.
